When I entered the study, I saw a stone table and a stone chair. A bookshelf. The bookshelves are made of high-grade mahogany, and although they are not supported by mana, they are not corrupted.

The books on the shelves haven't been touched for a long time, and there is a formation to remove dust, so it's still clean on it. The paper used in Taoist books is unusual, the most advanced ones must be incorruptible for a hundred years, and the higher ones can be not afraid of ordinary fire and water. In addition, there are some books that are obviously not Taoist books, and the mortal paper used can no longer be read after many years, and they will be broken when touched like clothes. There are also a few Taoist books, at the bottom of the bookshelf, it seems that the owner does not pay attention to it, Cheng Yunfan and the two of them easily put it into the Qiankun bag and walked out of the study.

The last one to enter is the Dan Room. The first thing I saw was a fiery red Danding the size of a water tank, and I found that there was a deep hole under the Danding, which should be the fire outlet of the earth. If Cheng Yunfan and the others have the cultivation of the foundation building period, they can draw the earth fire from this deep cave and use it for alchemy. The formations for gathering spirits and igniting fire in the Dan room are very complete, and the grade of Danding is above that of high-grade spiritual weapons. Cheng Yunfan saw a jade slip next to him, took a look, and saw that this was the introduction of the Dan furnace, this Dan furnace is called the Five Fire Bagua Furnace, which is actually a superb spiritual weapon, which was originally refined with five kinds of flames between heaven and earth, and engraved with the addition of the pill formation inherited from ancient times, and reciting the formula, this Dan furnace can be large or small, and change as you like.

Cheng Yunfan was overjoyed, and Lu Zhengyi was naturally overjoyed, but he didn't expect that the two of them really met the best treasure, so he naturally quickly tried the method to make the Dan furnace smaller and put it in the storage bag. And the gourds on the wall were empty, and there were no pills in them. The gourd is also processed by spells, and it is much better to preserve the pill than the popular jade bottle, and Cheng Yunfan naturally put it away.

After cleaning up the things in the cave, Cheng Yunfan and the others lay on the ground in the Dan room, relaxed, and fell asleep naturally.

When they woke up, they didn't know how long they had been asleep. These days, I have been in a hurry, fighting, breaking the ban, and getting injured, and I haven't had a good rest. In addition, the body lost too much blood and was very tired, and when the matter came to an end, Cheng Yunfan's spirit suddenly relaxed, and he fell asleep.

However, this sleep was quite comfortable, and after waking up, the two of them felt a lot better, and their spirits and spirits were back to their peak state. The two began to check what they had gained.

First count the storage bags of the previous few people, there are about five or six thousand spirit stones, seven or eight bottles of Qi refining period pills, more than a hundred and ten low-level charms of various colors, and the magic weapon has a total of three small swords, two fire fans, a golden flag, and a small bell, all of which are medium-grade spiritual weapons and low-grade spiritual weapons, and the two of them don't want to use them. The materials are also very rubbish, they are low-level things, and the exercises are also average.

The only useful thing is a small bottle of spirit dispersion and antidote, this is the cold and brave housekeeping baby, Cheng Yunfan put these away, and said to Lu Zheng with a smile: "This thing, we can also use it against the enemy in the future." ”

"Well, good things for killing people and setting fires, and robbing houses. Lu Zhengyi also said with a smile.

Then there are the things collected from the cave, first the purple-black storage bag, the bag itself is of the highest grade, the space is very large, and the prohibition is very clever, and it is comparable to the legacy of the Mixed Yuan Patriarch, Cheng Yunfan intends to leave it for Lu Zhengyi to use.

All the things were poured out, and there were really a lot of variety, and the first thing to take from it was a jade slip, which both of them took a fancy to, and it was also the only jade slip in the bag that looked of superior quality. It should be used above the foundation building period, Cheng Yunfan probed his divine sense into the jade slip, and the information in the jade slip poured into his mind like a tidal wave. After a cup of tea, the divine sense had already 'seen' the entire jade slip, and while looking at it, he roughly explained the situation, put down the jade slip, and the two of them were full of emotion.

"Sure enough, it's a murder and arson gold belt! Just this jade slip, this life-and-death fight is worth it. ”

The things in this jade slip are really rich, and the most important position is a foundation building exercise, called "Qinghua Longevity Formula". This is a wood-based exercise, but it's a pity that neither of them can use it. But there are many common senses and taboos in the exercises, which are very important to Cheng Yunfan and the others. This is also a comedy within a tragedy.

In addition to this exercise, there is also a Dan Sutra recorded in the Jade Slip - "The Immortal Pill Sutra". This Dan Sutra is not the same as the Dan Fang. Not to mention the popular "Alchemy Basics" in the market, the Danfang is just the formula and refining method of some elixirs, and the medicinal properties of various elixirs still need Cheng Yunfan and the others to find classics to learn and practice. The Dan Jing is different, the scripture itself shows that he is talking about the principles and rules of alchemy, and it is about the Dan Dao. It contains the principles of medicinal property harmony, substitution, and monarchy's subordination, as well as the prescriptions and refining methods of various practical pills, as well as the medicinal properties of elixirs, and the changes that will occur in alchemy. The grading method of Danding and its influence on alchemy.

It can be said that it is equivalent to the lifelong efforts of an alchemist in the Jindan period. Moreover, Yu Jian finally had some experience in cultivating elixirs, because the previous master practiced the wood system exercises, and he had special experience in this regard.

The most important thing is that there is a short paragraph of 1,000 words at the end of the jade slip, the name is "Taishang Danjing Fragments", as soon as he heard the word "Taishang", Cheng Yunfan was moved, it was about the refining of the best pills, and sure enough, there were some methods and tricks for refining the Taishang pills during the Qi practice and foundation building period, which was going to be passed out, which really shocked the world.

The two of them spent a cup of tea reading the jade slips, and it took another half a day to sort out these things. Most of the things in the jade slips were very esoteric to him, and he didn't have time to study them now, so he put them down after sorting them out. Now that you have this knowledge in your hands, you can learn it slowly in the future.

Suppressing the excitement that Yu Jian brought to herself, she began to sort out other things. What came out again were the Taoist books in the study, these things were not valued by the original owner, but Cheng Yunfan and the others, who gave priority to acquiring knowledge, still wanted to see what they were first.

"It seems that this senior is an alchemist who builds the foundation of the Great Perfection. Cheng Yunfan analysis.

"Well, the master said that alchemy and refining tools together are the most mind-consuming, and he can have the foundation building and Great Perfection cultivation, which means that he should be on the same level as the real people in the Jindan period. Lu Zhengyi guessed.

"We are a cultivator, and alchemy and refining tools are all auxiliary Dao techniques, and we can't take care of one or the other. Cheng Yunfan nodded and said, "This pill scripture contains the Zhuji Dan and the pills taken during the foundation building period, as well as the Ning Jin Dan that breaks through the bottleneck of the Jindan, it is said that after the Jindan period, the pills have little effect on the improvement of the exercises, except for the specific pills required to break through the realm, there is generally no need to take the pills." ”

Cheng Yunfan was also thinking about it, facing himself here, the most used were the three pills and pills in the foundation building period, but those materials were not found by one person's ability, but this pill was revealed, and it was enough to establish a sect.

The two of them paused for a while and continued to sort out their things, a silver shuttle, which should be a high-grade spiritual weapon, entered the field of vision of the two, and could not be used for the time being, so it was also put into the Qiankun bag, and then took out a scroll-like thing. It's obviously not a Taoist book, the material is very special, and it's a metal that Cheng Yunfan and the others don't know. The brown book cover was written with the words 'Xiuxian Sanji', maybe it was the notes of the original owner, but the two of them had low mana at this time but couldn't open it, so they could only put it back in the Qiankun bag.

Next is the elixir. Although there was no pill harvest in the pill room, there were many gourds full of pills in the Qiankun bag. Although so many years have passed, the pill has not changed much under the protection of the Qiankun bag and the gourd, and there will be no trouble with the expiration of the medicine.

The largest number of pills is Yunling Pill, which is an auxiliary pill that can be taken from the middle stage after the foundation is built, and the dosage is quite large. Cheng Yunfan checked the quality, and about half of them were medium-grade, and the others were also medium-to-high-quality. There is basically no lower grade, which shows that the original owner's alchemy skills are much higher than his own, and he is really an alchemy master.

"It seems that we don't need to refine the pill ourselves during the foundation building period, it is enough, and the extra part can be given away, so it is okay to sell it. ”

There is also an elixir that Cheng Yunfan does not know, and it must be an elixir that can be used in the later stage of foundation building. After looking for a long time, I didn't find the rarest Tsukidan. After confirming that there was no Tsukidan, the two were not disappointed. They've all got it anyway.

The two looked at each other and smiled, as if they had broken their greed in an instant, and smiled indifferently at the remaining twenty or thirty thousand spirit stones. As for the spirit grass, there are quite a few, most of them are about 100 years old, there are more than a dozen 500-year-old trees, and there are even two millennium years, which can only be used by Jindan and Yuanying monks.

The two of them sorted out their things, looked at each other and smiled, and they both sighed, "This harvest is really rich."

At this time, in a cave hundreds of miles away from the cave, Yun Ling was helping the master Yu Huai'an to heal his injuries, which had just ended.

"This time, thanks to you not going in and hiding outside, or I would have dumped my body in the wilderness right now. Yu Huaian said.

"What are we going to do with you and me, but this time it's really dangerous. I don't know what happened to Senior Brother Lu and Senior Brother Cheng. ”

"It should be no problem, even if they can't beat them, it's still no problem to escape and protect themselves, after all, Elder Lin's disciple, the master must have given the life-saving technique. Yu Huai'an said with some thoughts, but his voice quickly became melancholy, and he became helpless, "But this time, I am still too sorry for the two of them, I ran out by myself, but left him behind, I guess he thought I deliberately abandoned them, and he was disgruntled." ”

"Hey, you couldn't help it at that time, this secret method lasted a quarter of an hour at most, if you continue to fight, you will definitely die. It's better to break out and leave Qingshan without worrying about running out of firewood, I hope they can understand. If they really fall, we will hunt them down to the ends of the earth to avenge them. Yun Ling was kindly relieved on the side and swore on the side.

"I hope they are auspicious, but it's a pity that there are things in the cave. We spent so much effort to find the cave mansion and break the ban, but we cheapened the clouds and desolations. Yu Huai'an thought of the treasures in the cave mansion and sighed again.

"In the day, you're almost all right, let's go and have a look. Yun Ling proposed.

"Well, without further ado, we'll take advantage of the night tonight to take a look. Yu Huai'an never let go of the things that Dongfu left, and wanted to see the result, so he died of that heart.
